ABSTRACT:
An emission control system for a motor vehicle equipped with an automatic transmission having a band servo system including switching means for detecting the state of the band servo system and two vehicle speed switches respectively susceptible to two different vehicle speeds V.sub.1 and V.sub.2 (V.sub.1 <V.sub.2). The emission control system includes means for enriching the air-fuel ratio of the air-fuel mixture in an intake passage of the engines and exhaust gas recirculating means are so arranged that the air-fuel ratio of the air-fuel mixture is normally set on the rich side and the EGR ratio is made high. Correspondingly in the high driving range with a vehicle speed of lower the V.sub.2 the EGR ratio is made low, and in the high driving range with a vehicle speed of at least V.sub.2 the EGR ratio is made low and the air-fuel ratio is released from being set on the rich side.
